Ritchies, the geotechnical division of Edmund Nuttall, installed a 23m long semi-contiguous bored piled wall for the new Scottish Parliament Building in Edinburgh. The wall comprises 49, 10m long reinforced grouted piles and provides temporary support to Cannongate at the base of the Royal Mile. Following an initial excavation, further support was provided by eight, 14m long strand anchors with a working load of 500kN. The £100,000 contract for main contractor O'Rourke formed the last phase of the major groundworks for the parliament building basement.
